Wiper relay omission
« on: March 29, 2007, 11:38:31 »
I was trying to figure out why the wipers dont work.
Put a fresh motor and plugged it in only to ecounter the same problem-non functioning.
Tried the wiper motor to a battery and it worked.  Then checked for power to the plug end near the coolant tank, power in one prong.
Next looked at Achim's wiring diagram (Thanks Achim!) and see a relay that is supposed to be there.  
I admit I erroneously deleted it from the wiring when changing to the diesel wiring.
Now I need to add it back again, it should sit near the relays next to the booster, as I saw from the previous posts.  
Oh well, just wanted ot let you know that even the wisest one is stupefied.  
Guess part of this is the reason why I love to tinker under the hood and dash of the Pagodas.

Walter .... While reading your post, I got the feeling that you did not understand the operation of the wiper "relay".  It is a sequential switch that is switched off and on by a pulse from the stalk button. It is not a relay in the normal sense.
